Sarah Agnes Stap was a ship’s matron or  first class stewardess. According to her account, a young cabin boy put her in lifeboat 11 after initially rejecting it saying she was in her thirties. Since she was born in 1865, she was actually 47 at the time. She was the daughter of master mariner Captain Henry Stap and was born at sea. She passed away in 1937 at the age of 73 and was buried at Rake Lane Cemetery in Wallasey, England.

Her gravestone simply was marked “Stap” until Friends of Rake Lane Cemetery decided to step up and have her grave properly note she was a Titanic survivor. Stonemason Allen Roberts produced a headstone that now has the following on it:

Sarah Agnes Stap
1st Class Stewardess and Titanic Survivor

And to that all you can say is RIP.
